i just grabbed a random block
http://blockchain.info/block-index/440384/0000000000000000a1bf1c65136cbd618e356179fec857d583e7a9373ca8386d (269989)

and looked at the transactions in it..

within the first 20 transactions there were around 10 where the destination was at that time used address.

so is Luke JR telling us that the first transaction goes into this block(269989) the next transaction has to wait for the next block(269990)

and so on for the 10 addresses i looked at(269999) that there is causing atleast 1 hour 40 minute delay for that 10th transaction. and what about other transactions sent 10 minutes after(269989). they have no spaces in block(269990) through to (269999)

so lets say there were 10 used addressed transactions per block

in block(269990). after waiting 1 hour 40 minutes, each of those 10 transactions have to wait a further 10 minutes filling up blocks  (270000-270009) . making the 10th transaction sent at the timestamp of 269990 finally enter a block over 3 hours 20 minutes later

now imagine the transactions timestamped at the times of blocks 269991-270009.. imagine how long they have to wait. (300 transactions of used addresses waiting......)

Luke JR i guess you never watched the butterfly effect, or what happens when you throw a pebble into the water..
